class_docstr: Singleton object containing the current renderer configurations
docstr: The default renderer, or None if no there is no default
  
  If not None, the default renderer is used to render
  figures when the `plotly.io.show` function is called on a Figure.
  
  If `plotly.io.renderers.render_on_display` is True, then the default
  renderer will also be used to display Figures automatically when
  displayed in the Jupyter Notebook
  
  Multiple renderers may be registered by separating their names with
  '+' characters. For example, to specify rendering compatible with
  the classic Jupyter Notebook, JupyterLab, and PDF export:
  
  >>> import plotly.io as pio
  >>> pio.renderers.default = 'notebook+jupyterlab+pdf'
  
  The names of available renderers may be retrieved with:
  
  >>> import plotly.io as pio
  >>> list(pio.renderers)
  
  Returns
